Definitions

  • the invention relates to a device for forming a leno edge by means of mutually moving heald frames according to the preamble of the main claim
  • control cams are provided which cause the half-strand to change from one lifting hoist to the other lifting strand
  • the invention has for its object to achieve the control of the up and down movement of the half heddles without the help of magnets, so that despite the increasing number of strokes of the heald frames a safe entrainment and return of the half strands in the hoist guaranteed
  • the half-strands can be made from a wide variety of materials, ie no magnetically active material has to be used.
  • a plasma-coated aluminum can be used, which results in a reduction of the masses to be accelerated
  • the half foot is dovetail-shaped and is provided in the area of the half foot on the lifting hoist
  • Stops are to the dovetail-shaped half-hat Complementary foot design With this design, when the half heddle is lifted by the hoist, a movement of the half heddle transversely to the lifting movement of the hoist is already brought about.
  • the stops designed to be complementary to the dovetail-shaped half heddle foot, work simultaneously with the control cams provided in the area of the half hatch head and effect the same, for the lifting movement of the half necks transverse movement of the half strands
  • control cams provided in the upper region of the half strands that is to say in the region of the half-head, support this transverse movement of the half-strands and thus bring about the desired back and forth movement of the half-head towards the lifting heaters
  • the magnets provided in the upper area of the half heddles i.e. in the area of the half heddle head, support this transverse movement of the half heddles and thus bring about the desired back and forth movement of the half heddle head with respect to the lifting heaters if the half heddle is made of magnetically active material
  • safety stops are provided which are inserted into the free space of the half strands, which is formed by the two legs of the half strands
  • Fig. 1 three different positions of the lifting healds and the half heald guided therein, in
  • FIG. 2 shows on a larger scale the arrangement of a magnet in the area of the half-head on a lifting heald
  • FIG. 3 shows the guiding of the stand-up thread and the leno thread through the half-heald or the lifting heald
  • FIG. 4 a modified embodiment.
  • 1 and 2 denote two heddle support rails which are carried by heald frames indicated in the drawing and to which lifting healds 10 and 20 connect, the lifting healds 10 and 20 engaging over the heddle support rails by means of hooks.
  • the heddle support rails are not shown in the lower area of the illustration in FIG. 1.
  • the lifting strands 10, 20 have an approximately U-shaped cross section and accommodate a half strand 3 in the space thus formed, which consists, for example, of a plasma-coated aluminum.
  • the half-strand 3 In the area of the half-strand head HK, the half-strand 3 has a half-strand eyelet 4 through which the upright thread S, not shown in FIG. 1, is guided, as is shown in FIG. 3.
  • the half heald 3 has two legs 5 and 6, which are to
  • Half-heald foot HF extend out, but the half-heald foot is designed to be closed and, in the exemplary embodiment shown in FIG. 1, is dovetail-shaped, so that two stops 30 and 31 are formed.
  • the lifting strands 10, 20 are equipped with driving cams 7, 8, which are complementary to the dovetail tail-shaped half-strand foot are formed and engage in the space formed by the stops 30, 31
  • cams 15, 16 projecting into the space of the lifting strands 10, 20 in the lifting strands 10, 20 can be worked out, with the half-strand head also moving upward somewhat is rounded, so that this rounded half-light head HK can interact with the correspondingly shaped control cams 15, 16.
  • the cams 15, 16 are not absolutely necessary
  • sliding elements 13 and 23 are provided in the lifting straps 10, 20 for the leno thread, these sliding elements preferably being made of ceramic and compensating for the wear otherwise occurring due to the thread tension
  • Additional magnets 34, 35 can be provided to control the half flash 3
  • the driving cam 8 in connection with the stop 31 causes a slight movement of the half-strands 3 to the right, the half-strand head being likewise pulled to the right by the magnet 35 and the leno thread D being forced from the half-strand head HK to the left into the space designated by R, as can be seen in the illustration in FIG. 2.
  • the leno thread D is considerably lower than the upright thread S.
  • the up and down movement of the lifting strands 10, 20 thus not only causes an up and down movement of the half-strand eyelet 4, but at the same time also forces the actual half-strand 3 into a reciprocating movement, so that the leno thread D is deflected in each case and thereby the desired lathe binding is achieved.
  • the latter can also be made closed (FIG. 4) and the driver cams 7a and 8a can then be designed in a straight line.
  • control socks 32 and 33 are provided on the lifting strands in the region of the half-foot and preferably the top of the half-foot HF is bevelled so that this bevel can come into contact with the control cams 32 and 33 in such a way that the Half-strand foot HF is moved either to the right or to the left in the drawing.
  • the half flash 3 can be designed to be closed, thus has greater stability and, moreover, the type of control according to the invention enables the actual half flash to be made of non-magnetic - Chemical material can consist, for example, of plasma-coated
  • the provided sliding elements 13 and 23, which are preferably made of ceramic, increase the lifespan of the lifting strands 10, 20, since there are no longer any signs of wear

Abstract

L'invention concerne un dispositif pour former une lisière à tour anglais au moyen de tringles porte-lisse déplacées en alternance, portées par des lames, et au moyen de deux lisses de levée portées par la tringle porte-lisse, ainsi qu'au moyen d'une demi-lisse. Des cames d'entraînement faisant saillie dans la région de la demi-lisse et placées au niveau des lisses de levée coopèrent par liaison de forme avec des butées situées au niveau de la demi-lisse. Des éléments de commande, placés dans la région de la tête de demi-lisse au niveau des lisses de levée, guident la demi-lisse lors du mouvement de va-et-vient des lisses de levée vers chacun des côtés opposés.
